The present invention relates to fastening devices and its object is toprovide a cheap and convenient adjustable fastening for straps of allkinds. I

Twoapplications of the invention are'illustrated by Way of example inthe accompanying drawings, in which:

Figure 1 1s a plan View of the device applied to a shoe fastening,

Figure 2 is a perspective view of the device applied to a wrist watchstrap, and

Figure 3 is a longitudinal section through the tab part of the fastener.

Referring to Figure 1- a bridge member 1 is secured upon a short flap 2atthe side of the shoe, while a tab member 3 described more fully below,is mounted on the strap l which passes over the instep. To adJust thestrap a portion 5 passes through a loop 6 on the tab 3 and then back andin and out .of transverse slits 7 in the body of the strap which slitsare wider than the bent back portion of the strap end so that flatsurfaces of the strap the full width of the strap end lie in contactwith said end which is retained in position by friction when theadjusted strap is in use on the member on which it is fastened. Theportion 5 is shown set at its shortest. Naturally any number of strapsand fasteners may be used on the shoe.

In Figure 2 the same device is shown applied to a wrist watch, thelength adjustment 6 being effected as shown in Figure 1 by a portion 5passing through a loop 6 in the tab and in and out of slits 7 in thebody of the strap.

The tab fastening is illustrated in Figure 3 and comprises a recess tabpiece 8 carrying the loop 6'and having pivoted thereon at 9 a metalshoulder10. This shoulder is OF LONDON, ENGLAND, A COMPANY or GREATurged upward by a spring 11 held in place i by the pivot 9 and islimited in upward movement by a stop 7 which engages the edge of therecess. In use the tab is pushed through the bridge 1 when the shoulder10 is depressed. Vhen fully home the shoulder springs up and preventsthe tab from slipping back until the shoulder is deliberately depressed.v

' What I claim is:- p I I In a fastening for straps, shoes and the like,a loop in one member thereof, a strap end adapted to be adjusted passingthrough said loop and then bent back and passing in and out of a seriesof transverse slits in the body of thestrap wider than the bent backportion of the strap end so that fiat surfaces of the strap the fullwidth ofthe strap end lie in contact with said end which is retained inposition by friction when the strap is in,
